The universal joint (6) is connected with a steering engine. The steering column (8) is connected with a steering wheel. A corrugated tube (5) is equipped between and coaxially connected with the rubber coupler joint (7) and the steering column (8). With the arrangement (technical proposal), the torsional vibration produced by steering the vehicle and the axial vibration are respectively absorbed by means of the rubber elastic deformation of the rubber coupler shaft and the axial elastic deformation of the corrugated tube (5), so that the driving comfort of driver and the driving safety of vehicle are both improved.
Description
Technical field
The utility model relates to automobile steering system, and more particularly, the utility model relates to a kind of automotive steering structure tween drive shaft structure.
Background technology
At present, the steering gear of part automobile adopts the tween drive shaft that turns to of rigid attachment, the shortcoming of this rigid construction is exactly that the ground-surface impact has considerable influence to the vibration on the bearing circle, cause that chaufeur is easy to fatigue in the long-term driving procedure, and long-term high-frequency vibration also can obviously reduce steering gear, turn to life-span of electric switch and bearing circle.Adopt the tween drive shaft that turns to of independent band rubber shaft coupling knot on some automobiles, this connecting mode can only absorb the vibration of bearing circle circumferencial direction, and can not absorb the axial vibration of steering shaft.Travel for a long time, chaufeur is easy to fatigue, can not satisfy the driver comfort requirement.
The utility model content
Problem to be solved in the utility model provides a kind of motor turning tween drive shaft structure, its objective is that weakening vehicle ' produces circumferencial direction and axial vibration.
To achieve these goals, the technical scheme that the utility model proposes is: this car steering linkage mechanism tween drive shaft structure that is provided, comprise universal-joint, rubber shaft coupling knot and steering column, and above-mentioned member is being linked in sequence of coaxial line, described universal-joint is connected with steering box, described steering column is connected with steering handwheel, between described rubber shaft coupling knot and steering column, bellows is set, and is being connected of coaxial line with steering column with rubber shaft coupling knot.
The structure of described bellows is the not hollow tubular of shape of polyatomic ring, and its tube wall is shaped as waveform on the plane of dissecing along the bellows axis.
Bellows one end and rubber shaft coupling are bolted and are solidly connected, and the other end is fastenedly connected by steering column and steering handwheel.Bellows adopts metal bellow.
Rubber buffer is fixed between two flexure strips, and is fastenedly connected with tie bolt, and flexure strip is connected with joint yoke, and nyliner is captiveed joint with bellows.
The utility model adopts technique scheme, torsional direction that produces when making vehicle ' and axial the vibration elastic deformation and the axial elastic deformation of bellows of the rubber by rubber shaft coupling knot respectively absorb, thereby improved the driver comfort of chaufeur, and raising steering gear, turn to the life-span of electric switch and bearing circle, simultaneously by choosing suitable bellows tubing, the Rubber Parts rigidity that changes bellows ripple spacing and choose suitable buffer rubber gasket reaches abundant absorption vibration, weaken turning to the hysteresis purpose to greatest extent, improve running safety.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the rubber shaft coupling junction structure scheme drawing that the utility model adopted shown in Figure 1.
Number in the figure is: 1, buffer rubber gasket, 2, flexure strip, 3, tie bolt, 4, nyliner, 5, bellows, 6, joint yoke, 7, rubber shaft coupling knot, 8, steering column.
The specific embodiment
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the rubber shaft coupling junction structure scheme drawing that the utility model adopted shown in Figure 1.Structure of the present utility model shown in two width of cloth figure shows, the utility model is a kind of motor turning tween drive shaft structure, form by traditional universal-joint 6, rubber shaft coupling knot 7 and steering column 8, and above-mentioned member is being linked in sequence of coaxial line, universal-joint 6 is connected with steering box, and steering column 8 is connected with steering handwheel.Rubber shaft coupling knot 7 is made of joint yoke 6, tie bolt 3, flexure strip 2, rubber buffer 1 and nyliner.
The utility model improves driver comfort in order to absorb circumferentially reversing and axial vibration of producing in the running car, and the technical measures of taking are:
Between described rubber shaft coupling knot 7 and steering column, bellows 5 is set, and is being connected of coaxial line with steering column with rubber shaft coupling knot 7.Bellows 5 upper ends link to each other with steering handwheel by steering column.The structure of bellows 5 is the not hollow tubular of shape of polyatomic ring, and its tube wall is shaped as waveform on the plane of dissecing along bellows 5 axis.
The vibration of steering handwheel circumferencial direction, mainly the elastic deformation by the buffer rubber gasket 1 in the rubber shaft coupling knot 7 absorbs.
The axial vibration of steering handwheel, mainly the tube wall axial elasticity by bellows 5 is out of shape and absorbs.
Meanwhile, the elastic deformation of the buffer rubber gasket 1 in the rubber shaft coupling knot 7 also can absorb the axial vibration of certain steering handwheel; The tube wall axial elasticity of bellows 5 also can absorb the vibration of the circumferencial direction of certain steering handwheel.
Pass through the above-mentioned measure taked, the vibration of the torsional direction that produces on automobile steering device when making vehicle ' and axial vibration absorb by the elastic deformation and the distortion of bellows 5 axial elasticitys of the buffer rubber gasket 1 in the rubber shaft coupling knot 7 respectively, thereby improved the driver comfort of chaufeur, and improved steering gear, turn to life-span of electric switch and bearing circle.
In the specific implementation, can also further take following measures:
(for example can adopt different metallic materials by the tubing of choosing suitable bellows 5, or adopt nonmetallic material of construction), choose the wall thickness of suitable bellows 5 tubing, the bellows-shaped that changes bellows 5 and spacing and choose suitable Rubber Parts rigidity for buffer rubber gasket 1 and reach abundant absorption vibration, weaken and turn to the hysteresis purpose to greatest extent, further improve driver comfort and running safety.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
